When Baillot was in Leicester, he gave me a description of the horn-music which he heard at Moscow thirty years ago. It was at Prince Potemkin's, where two hundred performers executed a sinfony of Haydn, each with a trumpet that gave only a single note. It was a new idea to me, the advantages of which I apprehended would confer a power of accent unattainable by the ordinary way in which music is performed. A few years since a company of these musicians came to England, but they did not perform during my stay in town; and when they visited Leicester, I was unfortunately absent.
